Washington State Department of Licensing (DOL) Practice Test

When a school bus is stopped on a two-lane road with red flashing lights, everyone must come to a full stop in both directions. The red lights signal that children may be crossing or loading/unloading, and there could be kids in or near the roadway. You’re required to wait until the bus turns off its lights and resumes movement before proceeding.

This means you can’t just yield or slow down; you must stop completely and stay stopped until the bus is moving again. The rule applies to traffic traveling in either direction on a two-lane road, so stopping only in your own lane isn’t sufficient. Proceeding slowly or continuing would create a safety risk for children.
